2005 Malibu Maxx...the strangest wagon



This is essentially the same car I just picked up...on the rear I want to reduce some drag.

Would it be better to extend the roofline at a slight angle downwards instead of the factor spoiler which you can see tapers slightly upwards?
Or would it be better to add a second wing on the rear 'notchback'?

I'm not looking to do anything super dramatic as a full boattail but I think I could make some substantial gains with very little effort on the rear.

Thoughts?

gains

The MAXX belongs in the nether world of design.It's not a proper notchback,and it's not a proper squareback.
It is possible that GM has already optimized the C-pillars such that for what it is,it's already optimized for drag.
If you wanted to do some Cardboard And Duct tape (CAD) experiments,you might mess around with a Kamm-like extension extending to the rear of the hatch.
Here is a study Hucho did at Volkswagen with the 1st-gen Golf/Rabbit.Around the 'Template' line he got the lowest drag.

You might be interested in this video, since the rear profiles are similar :

I have always considered it as a hatchback, not a wagon. BTW you might consider to take a look at the spoiler used in the Opel Corsa B GSi.
